Electron microscope - Wikipedia, the free encyclopedia (1789 words) |
 | The electron microscope is a microscope that can magnify very small details with high resolving power due to the use of electrons as the source of illumination, magnifying at levels up to 2,000,000 times. |
| The first practical electron microscope was built by Eli Franklin Burton and students, Cecil Hall, James Hillier and Albert Prebus, at the University of Toronto, Canada in 1938. |
| Unlike the TEM, where electrons are detected by beam transmission, the Scanning Electron Microscope (SEM) produces images by detecting secondary electrons which are emitted from the surface due to excitation by the primary electron beam. |
| Micrograph - Wikipedia, the free encyclopedia (123 words) |
| A micrograph is a photograph or similar image taken through a microscope or similar device to show a magnified image of an item. |
| To produce a micrograph, a camera is affixed to a microscope either in place of the eyepiece or a specialist microscope is used which has a camera and eyepiece arrangement. |
| An electron micrograph is a micrograph prepared using an electron microscope. |
